• LiveCD Boot/Install

  - by Jon

  I have recently built a new computer and have been looking to dual-boot alongside Windows. Trying to boot/install off Ubuntu/Dedora/Arch live CDs has failed across all distros and I keep getting the error: [34.5173939] ata9.00: exception Emask 0x52 SAct 0x1 SErr 0xffffffff action 0xe frozen [34.517403] ata9: SError: {RecovData RecovComm UnrecovData Persist Proto HostInt PHYRdyChg PHYInt CommWake 10B8B Dispar BadCRC Handshk LinkSeq TrStaTrns UnrecFIR DevExch } [34.517413] ata9.00: failed command: READ FPDMA QUEUED [34.517420] ata9.00: cmd 60/08:00:00:6d:70/00:00:74:00:00/40 tag 0 ncq 4096 in [34.517420] res 40/00:01:00:00:00/00:00:00:00:00/00 Emask 0x56 (ATA bus error) [34.517433] ata9.00: status: { DRDY } [34.667134] ata10.00 exception Emask 0x52 SAct 0x1 SErr 0xffffffff action 0xe frozen [34.667134] ata10: SError: {RecovData RecovComm UnrecovData Persist Proto HostInt PHYRdyChg PHYInt CommWake 10B8B Dispar BadCRC Handshk LinkSeq TrStaTrns UnrecFIR DevExch } [34.667153] ata10.00: failed command: IDENTIFY PACKET DEVICE [34.667159] ata10.00: cmd a1/00:01:00:00:00/00:00:00:00:00/00 tag 0 pio 512 in [34.667160] res 40/00:01:00:00:00/00:00:00:00:00/00 Emask 0x56 (ATA bus error) [34.667170] ata10.00: status: { DRDY } I am using a new ASUS Z77 Sabertooth motherboard with a Seagate Barracuda ST1000DM003 1TB 7200RPM hard drive. I am not entirely sure why I can't even boot off the live CD? Any ideas? Hi thanks for the quick response. All Distros were direct download from their respective websites, I have tried both CD boot with all distros and USB boot with Arch only. I have just updated my BIOS as well an am still receiving the same error. The fact that it happens on CD and USB tell's me it's not an optical drive issue. All information I can find on this seems to relate to hard drives failing on already installed linux boxes or faulty SATA cables. I am a bit confused why this issue would be preventing a CD/USB boot though. Is there any more info I can provide that might help uncover the source of the problem? Cheers, Jon

• Leveraging .Net 4.0 Framework Tools For Encrypting Web Configuration Sections

  - by Sam Abraham

  I would like to share a few points with regards to encrypting web configuration sections in .Net 4.0. This information is also applicable to .Net 3.5 and 2.0. Two methods can work perfectly for encrypting connection strings in a Web project configuration file:   1-Do It All Yourself! In this approach, helper functions for encrypting/decrypting configuration file content are implemented. Program would explicitly retrieve appropriate content from configuration file then decrypt it appropriately.  Disadvantages of this implementation would be the added overhead for maintaining the encryption/decryption code as well the burden of always ensuring sections are appropriately decrypted before use and encrypted appropriately whenever edited.   2- Leverage the .Net 4.0 Framework (The Way to go!) Fortunately, all needed tools for protecting configuration files are built-in to the .Net 2.0/3.5/4.0 versions with very little setup needed. To encrypt connection strings, one can use the ASP.Net IIS Registration Tool (Aspnet_regiis.exe). Note that a 64-bit version of the tool also exists under the Framework64 folder for 64-bit systems. The command we need to encrypt our web.config file connection strings is simply the following:   Aspnet_regiis –pe “connectionstrings” –app “/sampleApplication” –prov “RsaProtectedConfigurationProvider”   To later decrypt this configuration section:   Aspnet_regiis –pd “connectionstrings” –app “/SampleApplication”   The following is a brief description of the command line options used in the example above. Aspnet_regiis supports many more options which you can read about in the links provided for reference below.   Option Description -pe  Section name to encrypt -pd  Section name to decrypt -app  Web application name -prov  Encryption/Decryption provider   ASP.Net automatically decrypts the content of the Web.Config file at runtime so no programming changes are needed.   Another tool, aspnet_setreg.exe is to be used if certain configuration file sections pertinent to the .Net runtime are to be encrypted. For more information on when and how to use aspnet_setreg, please refer to the references below.   Hope this helps!   Some great references concerning the topic:   http://msdn.microsoft.com/en-us/library/ff650037.aspx http://msdn.microsoft.com/en-us/library/zhhddkxy.aspx http://msdn.microsoft.com/en-us/library/dtkwfdky.aspx http://msdn.microsoft.com/en-us/library/68ze1hb2.aspx

• Wake laptop when lid is opened?

  - by crackout12

  I have a SAMSUNG laptop, which by the experience in the last months, has been a great one. I am actually implementing some functionality to it, and since I noticed, I am able to wake up my laptop from sleep by just opening the lid on Windows 7, however, I need to press to power button to wake up in Ubuntu. Using a program called i-nex, I noted that the kernel DOES dettect a "lid switch", and I am looking forward to use it to wake up function. Any ideas? UPDATE: Thanks @yossile for bringing up some clues! However, output of command cat /proc/acpi/wakeup does not show the LID device. I still tried the second set of commands you gave me with no effect. Then I tried experimenting, guessing that LID should be named by other value, so I tried enabling the others. No victory so far. But I noticed that devices that did not have any pci listings were disabled at all time no matter what I tried. Here is the output of command cat /proc/acpi/wakeup: root@samsung:~# cat /proc/acpi/wakeup Device S-state Status Sysfs node PCE4 S4 *disabled pci:0000:00:04.0 SBAZ S4 *disabled pci:0000:00:14.2 P0PC S4 *disabled pci:0000:00:14.4 GEC S4 *disabled PE20 S4 *disabled pci:0000:00:15.0 PE21 S4 *disabled PE22 S4 *disabled pci:0000:00:15.2 PE23 S4 *disabled PWRB S5 *enabled So maybe it could be that LID is either GEC,PE21, or PE23? Still, there is /proc/acpi/button/lid/LID/state file which shows that LID is opened. Any more ideas?

• Apt-get saying "Unable to correct problems, you have held broken packages."

  - by YatharthROCK

  TL;DR: sudo apt-get install ... saying "Unable to correct problems, you have held broken packages." The problem I was trying to get the WebApps feature for PP and QQ following this blog post. I ran the sudo add-apt-repository ppa:webapps/preview command to add the repository, but i got a connection error. Since I know my current ISP gives a shaky connection, I tried again and sure enough, it worked. Then I ran sudo apt-get install unity-webapps-preview, but I realized we had to update apt-get first, so I hit Ctrl + C to stop it. Then I ran sudo apt-get update which worked w/o a fuss, but when I ran sudo apt-get install unity-webapps-preview again later, it showed an error message. Here's the dump: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: unity-webapps-preview : Depends: xul-ext-unity but it is not going to be installed Depends: xul-ext-websites-integration but it is not going to be installed Depends: xul-ext-webaccounts but it is not going to be installed E: Unable to correct problems, you have held broken packages. I think this might be because of me interrupting the earlier command. It hadn't got a chance to output anything, though — I stopped it pretty fast. What I tried I have tried running a number of commands:- sudo apt-get install --fix-broken sudo apt-get autoclean sudo apt-get autoremove sudo apt-get -f install sudoapt-get install ppa-purgeandsudo ppa-purge ppa:webapps/preview` Even after running sudo apt-get upgrade after every try, none of them worked. Research I tried searching Google, looking at a couple of forums and searching on AU, but to no avail. Help would be appreciated.

• Terminal app on Mac OS X - normal keys

  - by Matthew

  There are some default terminal things different for the Mac (for example, Command C to copy and Command V to paste rather than simply highlighting/right clicking). These are fine with me. What bothers me though is I can't figure out how to click or use the F keys. The main app I have problems with is htop. Htop supports clicking on column names to sort, etc. Also, to exit the app, you are supposed to press F10. But F10 simply mutes my volume. I've tried different combinations of things like alt F10. I usually have to quit htop by pressing CTRL-C Any ideas on how to get normal terminal behaviors? Normal meaning linux

• Include Binary Files in DEB package

  - by user22611

  I need to build a DEB package from mainly Node.js Javascript files, but it should include some binary files as well. They are listed inside debian/source/include-binaries. Otherwise I get the error message dpkg-source: error: unrepresentable changes to source The command in question is: bzr builddeb -- -us -uc After adding the file include-binaries, when running bzr builddeb -- -us -uc again, now I get a different error: It says dpkg-source: error: aborting due to unexpected upstream changes, see /tmp/mailadmin_0.0-1.diff.n6m5_6 I have no idea how to get rid of this. In the next line of output it tells me dpkg-source: info: you can integrate the local changes with dpkg-source --commit But if I run this command in the build area of my package, it gives me the unrepresentable changes to source error message again, even though debian/source/include-binaries is present in the build area as well. I am missing the way out of this... I tried deleting all files that are produced by the build process, still no success. Further details: The target directory is /opt/mailadmin. Since this directory is unusual, I listed it in the file debian/mailadmin.install (which contains one line:) opt/mailadmin opt/ The bzr builddeb process uses this file as expected.

• Using Supervisord, how can I start a brand new worker via supervisorctl without restarting other workers?

  - by cballou

  Let's say I have a number of existing workers running in supervisord. I want to add a new worker to the group as well as start the new worker. I perform the following steps: I modify the file /etc/supervisor/supervisord.conf and add the new worker config Back on the command line, I enter sudo supervisorctl I run reread to read the new configuration file settings. Attempting to run start workers:exampleWorkerName gives the error workers:"exampleWorkerName": ERROR (no such process) So, my question is, how can I start this new worker process without affecting my other existing workers? I'd rather not perform a supervisorctl reload or /etc/init.d/supervisord restart command.

• have a bash script remotely shutdown another computer on the lan

  - by gletscher

  Hi I want to write a bash script that when called shuts down another computer on the lan. Maybe using ssh? The other computer is an ubuntu machine. Now I'm not sure how to send e.g. a sudo shutdown -h now command from withing a bash script to the ssh after logging in. Also I'm not sure how to obtain the rights for the sudo command, hence how to handle the communication between the server and client from within a bash script. Any suggestions are greatly appreciated.

• How do I install Postgres Graphical Installer?

  - by Tusar Das

  I am a newbie in using Ubuntu (more precisely never used linux except the production deployment ). Now I choose to hold a grip on the system and intalled a latest 11.10 Ubuntu in my 32 bit Intel** desktop. In this machine **I have a 'administrator' user 'tusar'. I want to install the PostgreSQL graphical version so downloaded this file postgresql-8.4.9-1-linux.bin from here Now If run the file with ./filename command (refuses if I am not root), it opens up the graphical interface and completes the installation (creates user postgres and ask for password, wont complete if I dont give valid password). I checked with /etc/inint.d/postgresql-8.4 status , that postgres is running. But the problem is I am unable to open the GUI (I installed it in /opt/Postgresql ), its telling permission denied even if I am logged in as 'tusar'. Then I tried using the su postgres command and it directly changed the user without password. Now if I run the psql , createdb , its prompting me to install the postgres-client-package but this utilies are already installed and I can view them in my /opt/Postgresql/8.4/bin folder. I can run query through my JDBC utility programs but unable to use neither terminal nor the graphical interface (although I can see pgAdmin3 is there ). Urgent help needed. I have used this guide for the installation.

• How do I install kivy?

  - by aspasia

  I was trying to install Kivy (by following the instructions here). I downloaded and installed all packages where the installation process went through without giving me any errors. However, when later I enter below command; sudo easy_install kivy It looked like it was going to work but it ends with an error by displaying following lines, which I don't comprehend: Detected compiler is unix /tmp/easy_install-BtOA_u/Kivy-1.8.0/kivy/graphics/texture.c:8:22: fatal error: pyconfig.h: No such file or directory #include "pyconfig.h" ^ compilation terminated. error: Setup script exited with error: command 'x86_64-linux-gnu-gcc' failed with exit status 1 I saw a similar question asked as; Problem with kivy installation. However, this didn't work for me though the question suggests installing libgles-mesa-dev-lts-raring which I did as below; sudo apt-get install libgles-mesa-dev-lts-raring which then gave below; E: Unable to locate package libgles-mesa-dev-lts-raring (sorry for being so specific and perhaps obvious, but I'm in the early stage of learning my way around linux). This user was running Ubuntu 12.04, and most other questions related to this I've seen came from people with a different release from mine, which has led me to believe that that is the reason why the suggestions to those didn't solve my problem. I'm using Ubuntu 13.10

• please help me understand libraries/includes

  - by fiftyeight

  I'm trying to understand how libraries work. for example I downloaded a tarball and extracted it. Now I do "./configure", it searches in pre-defined directories from what I understand for certain library files. What does it do then? it creates a makefile, and the makefile contains the paths to these libraries? than I do "make", it complies the source code and hard-codes the locations of the libraries? am I correct? I do not really understand if libraries are files with pre-defined paths or the OS somehow gives access to the libraries through system calls. another example, I complied something on my computer than moved it to a remote server, the executable needs mysql libraries to work, the server has mysql but for some reason when execute the file it tells me "can't find libmysqlclient.so.16". is there a solution for this? is there a way to know where is tries to locate this file or give it another path? I can't compile it on the server since it has no compiler and I don't have root access to install packages last question is if in the sequence "./configure","make","make install" the "make install" command is the only one that actually puts files outside the directory in which these files reside? if for example the software will be installed in /usr/local/ is the "make install" command the only one that will require "sudo" before it? let me see if I got it correctly: "./configure" creates the Makefile according to the location of various files on your system. "make" compiles the source code according to this makefile. and "make install" moves the files to their appropriate location. I know this has been very long I thank anyone who had the patience to read my question :)

• Happy New Year! Back to school :)

  - by Jim Wang

  A brand new year is upon us and it’s time to get cracking with WebMatrix again…and go back to school :).  Last year we ran a successful product walkthrough for WebMatrix Beta 2 with our students from around the world, gathering awesome feedback for the final version of WebMatrix which is coming soon!  I’d like to take this chance to thank all the students who participated in this effort…you have really helped make the final product much better than it would have been otherwise. In 2011, we’re looking, as always, at bigger and better things.  One of the ideas that has been floating around is the concept of a WebMatrix college course that you could take for actual credit.  Of course, this is going to require coordination with college educators, but we think we’re up to the challenge :) If your school is still using an antiquated language to teach their web development 101 course, and you’d like to switch to WebMatrix, we’d like to hear your voice – better yet if you have contacts from your school and would like to be one of the first to give the program a try!  Comment on this post or email wptsdrext at microsoft.com.  We look forward to partnering with you guys ^^.

• Android&ndash;Finding your SDK debug certificate MD5 fingerprint using Keytool

  - by Bill Osuch

  I recently upgraded to a new development machine, which means the certificate used to sign my applications during debug changed. Under most circumstances you’ll never notice a difference, but if you’re developing apps using Google’s Maps API you’ll find that your old API key no longer works with the new certificate fingerprint. Google's instructions walk you through retrieving the MD5 fingerprint of your SDK debug certificate - the certificate that you’re probably signing your apps with before publishing, but it doesn't talk much about the Keytool command. The thing to remember is that Keytool is part of Java, not the Android SDK, so you'll never find it searching through your Android and Eclipse directories. Mine is located in C:\Program Files\Java\jdk1.7.0_02\bin so you should find yours somewhere similar. From a command prompt, navigate to this directory and type: keytool -v -list -keystore "C:/Documents and Settings/<user name>/.android/debug.keystore" That’s assuming the path to your debug certificate is in the typical location. If this doesn’t work, you can find out where it’s located in Eclipse by clicking Window –> Preferences –> Android –> Build. There's no need to use the additional commands shown on Google's page. You'll be prompted for a password, just hit enter. The last line shown, Certificate fingerprint, is the key you'll give Google to generate your new Maps API key. Technorati Tags: Android Mapping

• How do I configure Ruby On Rails on windows XP with APACHE and MYSQL

  - by Gaurav Sharma

  Hello Everyone, It has been quite some time I am struggling to get Ruby On Rails working on my System which is having Windows XP operating system. I am trying to configure ROR to use apache and mysql so that I do not have to install additional servers to run ruby on rails. I also tried InstantRails but faced same problems. I went through the tutorial mentioned in getting rails to wrok on a windows machine running xampp and did all the steps which were necessary. All went fine (installing rails, running the ruby, gem and rails command from command prompt) but when I tried to run my application by typing localhost:3000/say/hello nothing happened and I was redirected to the google page for searching to this keyword. Please help me Thanks

• Live chat solutions

  - by Lèse majesté

  What good live chat/live help solutions are available (preferably for use on a site hosted on a LAMP stack and free)? I'm looking for a way to allow our sales and customer service reps to talk directly with visitors to our site. I've looked at phpopenchat, but it looks very unpolished. The only other free live chat app I've come across looked egregious. The aesthetics and UI design alone made me shudder to think what the underlying code might look like. This isn't a critical feature, and it wouldn't be hard to code up myself, so I'm not really looking for commercial software or paid services (unless there's a really compelling reason to use them). I'm just wondering if any other webmasters have come across a satisfactory free/open source solution for providing live customer support on their website. As a side note, live voice chat would also be an option, but it has to be be designed (or customizable) for customer support rather than a public chatroom. Edit: Looking at the responses, it looks like there probably aren't going to be many free solutions for this type of business-oriented chat solution, so feel free to post answers even if they are commercial solutions as long as they're a good value. Also feel free to post any alternate live support solutions (such as the Skype recommendation) that could be in someway integrated with a website. This will give me a good lay of the land for what people are actually using for live support, and I think will be more helpful to others reading this question.

• Is the output of Eclipse's incremental java compiler used in production? Or is it simply to support Eclipse's features?

  - by Doug T.

  I'm new to Java and Eclipse. One of my most recent discoveries was how Eclipse comes shipped with its own java compiler (ejc) for doing incremental builds. Eclipse seems to by default output incrementally built class files to the projRoot/bin folder. I've noticed too that many projects come with ant files to build the project that uses the java compiler built into the system for doing the production builds. Coming from a Windows/Visual Studio world where Visual Studio is invoking the compiler for both production and debugging, I'm used to the IDE having a more intimate relationship with the command-line compiler. I'm used to the project being the make file. So my mental model is a little off. Is whats produced by Eclipse ever used in production? Or is it typically only used to support Eclipse's features (ie its intellisense/incremental building/etc)? Is it typical that for the final "release" build of a project, that ant, maven, or another tool is used to do the full build from the command line? Mostly I'm looking for the general convention in the Eclipse/Java community. I realize that there may be some outliers out there who DO use ecj in production, but is this generally frowned upon? Or is this normal/accepted practice?

• lirc_zilog IR transmission no longer working with HD-PVR on 12.04

  I have been running a ubuntu 10.04 with a patched version of lirc_zilog for two years. I upgraded to 12.04 and lirc_zilog is no longer working with my HD-PVR.

• What does Skyrim Creation Kit's NPC class do?

  - by pseudoname

  I'm trying to change it with the setclass console command Based on the UESP wiki it looks like it just governs stat gain for leveling, but based on the Elder Scrolls wiki it seems to only control their combat AI. Obviously it does at least one or both of those - what does it actually do, and does it do anything else? __ Ex: if change Lydia from warrior1handed to vigilantcombat1h with the console command 000A2C94.setclass 0010bfef will it have any unintended side effects that aren't immediately apparent other than letting her use the alteration and healing spells I just gave her with console and setting her stats in a way that works for that? Will it do something weird like mess with her factions or ability to join as my follower? Or mess with her health scaling as she levels? Something hard to notice until alot of time went by? @desaivv* I was trying to do it with 000A2C94.setclass 0010bfef wasn't sure if it'd cause hidden issues only showing after hours of play or if i made a new character with the same bat file. but the creation kit sounds like an idea too, i'll have to see how complicated it is. it might just show what it'd do or have some easier way to change her behavior to add spells. I'll try it and see if anything obvious shows up short term just wasn't sure if it had known long term problems

• Today I talk about you

  - by BuckWoody

  Some time back I posted a blog entry (mirrored here and here) asking you how you design databases. Out of those responses, my own experience, studies I read, and interviews I conducted, I collected a wealth of data. Thanks for your responses. So what am I going to do with that information? Well, all along I had planned for that to be used today. I am giving a presentation at an event called “TechReady” called “How Your Customers Design Databases”. This is a Microsoft-internal event, where technical professionals like myself, salespeople, and the product team get together to talk about what has been working, what doesn’t, what is coming and hopefully (fingers crossed here) what the product team can do to help us help the SQL Server community. I’ve mentioned before that I teach database design as part of a course I run at the University of Washington. I’m also planning to give a mini-lecture from that series at TechEd 2010, so if you’re coming stop by. I’d love to meet you. So today I talk about you – thanks for the input. I hope you and I can make a difference in the product. Might take a while, but it’s nice to know your voice is being heard.

  I'm trying to use "sox" to mix some audio files. The command works great on my Mac terminal sox -m audio.wav "| sox upload.wav -p trim 2 1 pad 6" final.wav This mixes (not concatenate) audio.wav and a section of upload.wav from the 2nd second to the 3rd second and adds 6 seconds of padding in the front, and outputs to final.wav Now the problem is, the SAME EXACT command does NOT work my Amazon EC2 RHEL box. (sox is installed correctly). I get the following error sox soxio: Can't open input file `| sox upload.wav -p trim 2 2 pad 6': No such file or directory For some reason RedHat doesn't like the double quotes. Even though it is documented to be used this way. Thanks for your help!

• FTP Issue when connecting to a debian machine from windows

  - by erin c

  I have a .net application which copies bunch of files to a specific FTP folder on a debian machine on periodical basis, ftp folder has 755 mod, owner of the directory is the ftp username that I authenticate in .net application. So far I tested this application with bunch of debian boxes, my initial attempts generally fail with following message if I try it with a debian machine that I haven't tried it before: "remote server returned an error 550 File unavailable" When I see this error, I log onto another debian machine on my network, and I try FTP'ing the debian box that returns the error message from command line. I generally "put" a very small file to the folder in question, right after that windows application starts copying files successfully via FTP. It is as if my command line ftp operation fixes the problem and makes debian compatible with my .net application. I checked permissions before and after the problem, it doesn't look like what I did changed anything, I am at loss understanding why this problem occurs and why it is fixed with my silly hack. Can anybody tell me where to look at next to fix this extremely annoying issue?

• Many commands are not found by zsh

  - by Denny Mueller

  If I tab autocomplete, most of the time I get errors. Let's say I do a vim tab to look for the files in the folder. It just jumps to the next command line. Or let's say I press tab after typing rvm use 2.0.0 --default I will get zsh: correct 'rvm' to 'rvim' [nyae]?. If I say no, I get a command not found error. Also if I press tab after typing ruby -v, zsh wants to correct to _ruby -v. Any known bug or any help for this?

• rsync to EC2: Identity file not accessible

  - by Richard

  I'm trying to rsync a file over to my EC2 instance: rsync -Paz --rsh "ssh -i ~/.ssh/myfile.pem" --rsync-path "sudo rsync" file.pdf [email protected]:/home/ubuntu/ This gives the following error message: Warning: Identity file ~/.ssh/myfile.pem not accessible: No such file or directory. [email protected]'s password: The pem file is definitely located at the path ~/.ssh/myfile.pem, though: vi ~/.ssh/myfile.pem shows me the file. If I remove the remote path from the very end of the rsync command: rsync -Paz --rsh "ssh -i ~/.ssh/myfile.pem" --rsync-path "sudo rsync" file.pdf [email protected] Then the command appears to work... building file list ... 1 file to consider file.pdf 41985 100% 8.79MB/s 0:00:00 (xfer#1, to-check=0/1) sent 41795 bytes received 42 bytes 83674.00 bytes/sec total size is 41985 speedup is 1.00 ...but when I go to the remote server, nothing has actually been transferred.
